Wedge 1 represents the volume enclosed by z=0, x=0, x=y^2, and y+z=1. The equations are printed on the model. There is a classic Multivariable Calculus problem which asks you to express the volume of this volume using a triple integral in six different orders.

This model was designed and printed by my WLU summer research student Ryan McDonnell ('17). Details about the construction can be found at http://mathvis.academic.wlu.edu/2015/06/26/wedge-1/ and

This object was made on a MakerBot2X. We used the following settings:
2 shells
0.20mm layer height
10% infill (hexagonal pattern)
No supports
Raft off
